You are asking me - an individual - what good will do to the game if I prove that EA/DICE are lying to the community will do to the game:
It could make DICE/EA publicly admit that the game is in a bad place right now, forcing them to commit with specific content and delivery dates, instead of giving vague info and cutting out game modes to hide the thinning player-base. Realizing they need to work hard and fast would give the game more content sooner, instead of "Guys chill. No rush to deliver anything asap. Our PR guys and game changers keep the players under control with hopes"
Since you are supporting them, can I ask you same question reversed? What good lying to the community will do to the game? Keeping in mind that being vague, is still lying, because each player believes whatever they are hoping for, even if its not true.
Giving false hope that the "unknown content" that is "coming soon" will be whatever each individual wants and will be delivered before they get bored of the game?
Mentioning that "there are more maps in development than ever have been in Battlefield history" but hide the fact that most of them will most probably be small maps for the new 5v5 mode rumored?
Cutting game modes to give the false impression that players still enjoy the game instead of slowly abandoning from boredom/bug rage? Making players think that it must be my own "taste's" fault that I don't enjoy a buggy game with lack of content and I should give it another chance?
Give false impression about patches fixing bugs when every release introduces new? I have made a list with actual bugs in January here: https://answers.ea.com/t5/Bug-Reports/I-made-an-ACTUAL-bug-issues-list-In-just-2-days/td-p/7352356 most of them are still in the game (or others introduced and not mentioned)
Hide the fact that promised features got cancelled? Body dragging, "crazy" limps and cosmetics
What good all these things will do to the game? Drive a few desperate micro transactions or sales? That is not helping the game, that is helping EA squeeze a little bit of money little before killing the game.
Here is what needs to happen.
The "coming soon" model needs to end and an official roadmap should be released in the form of:
Conquest large map named "______" will be released on x/x/2019 - Weapon "_____" will released on x/x/2019 - Elite Skin "____" will be released on x/x/2019
If there will be 5 new conquest maps until the end of the year + a new weapon and skin every week we will finally be delivered with the minimum content we are owed based on past titles. If you believe i am being unreasonable, I can remind you that 15 maps is still less than what bf1 had in 1 year.
Even if there is the ability to deliver only 1 map by the end of the year and 1/4 of the weapons I claim we are owed, the commitment to that would be far more appreciated than giving false hope for content. If you can manage to squeeze something extra, its always appreciated. Surprise content is always welcome and makes players happy. Expecting content (because of vague promises) and getting nothing makes players mad.
DICE should calculate the minimum amount of content they can deliver until the end of the year, assuming they will be working half the time they plan to, and commit to that with a road-map which should be released ASAP. If they don't even manage to deliver that, it means there is something seriously wrong in the studio and its really not about the game or EA. Phrases like "you can't predict development", "you cant set deadlines", "you can't commit to deliver content and/or fix bugs" are just excuses we have been hearing from DICE since ...ever. There are many developers who are capable of doing all these things while constantly providing content: Blizzard, Epic, Rockstar, Valve, CD Projekt Red even Ubisoft. That means they are doing something right and/or DICE is doing something wrong. Now its their job to find what these things are, shape up, or accept their failure and close shop.
